COMBINED SOCKET-COVER AND SHADE-HOLDER.

Specification of Letters Patent. Application filed April 7, 1912. Serial No. 391,287.

the-same, is thenovel socket cover and shade holder A, made in this instance in two parts, a cap 12 fixed in place on the arm 11, and a skirt 13 removabl connected to thecap and provided with fhstening' means, such as screws, 14 for attaching a shade 15 of any suitable type to the bottom of the skirt or shade holder, as shown. The cap 12 is here shown in the sha e of a dome with a central hole through which the threaded end of the bracket arm 11 extends for the attachment To all whom it may concern:

Be it known that I, CLARENCE W. Lucas, a citizen of the United States, residing at Decatur, in the county of Macon and State of Illinois, have invented new and useful Improvements in Combined Socket-Covers and ShadeHolders, of which the following is a specification.

This invention relates to a socket cover and shade holder for incandescent electric lights, and has for its object toprovide a neat and ornamental attachment for electric thereto of the light fixtures which pensive and attractive to the eye, and capable of holding a shade with great steadiness on an electrolier or other electric lamp supporting bracket.

The socket cover and shade holder of the present invention comprises two separable parts, one part being normally secured to the bracket by the lamp socket and partly covering the top of the same, and the other part capableof attachment to and detachment from the fixed part and inclosin the body of socket. Each of the parts o the shade holder is made of a single piece of metal pressed, spun or otherwise formed complete with integral fastening means so that no movable or attached'parts, such as screws, bolts, springs and the like, which may be lost or .worn, are required. The simplicity of construction and the firmness and rigidity of the separable connection between the parts are notable features of the invention. Furthermore, because the lower ed e of the cap or upper part of the shade holder lies above the point of separation between the body of the lamp socket and its top, the electric current wires can be connected to the switch in the socket without trouble.

In the accompanying drawing Figure 1 is an elevation of the improved socket cover and shade holder in position; Fig. 2 is a sectional view of the same; Fig. 3 is a perspective view of the shade holder removed; Fig. 4 is an enlarged sectional view of a detail of the invention.

In the drawing wherein like reference characters are used for the same parts in all the figures, 10 indicates an incandescent electric lamp socket, of any known type,'se-' cured on an arm 11 of an electrolier or other fixture.

Surrounding the socket 10, and inclosing shall be simple, inextop 16 of the lamp socket on said threaded end and firmly in place. Near its which screws holds the cap lower edge, curve 17 and then bent downwardly at a sharp angle 18 to form a straight concentric band 19 at the base of which is an outwardly' curved bead 20 turned inwardly at the bottom to form a shoulder 21 for supporting the shade or skirt 13 in a manner to be described'later. The shoulder 21 which has, preferably, a slight upward inclination, see Fig. 4, may terminate with a downwardly projecting flan e 22 inline with the straight concentric band 19, which flange serves to stiffen the shoulder and prevent deformation thereof when the cap is made, as itusually is, of sheet metal, and in connection with the bandit forms a guide for the upper end' of the skirt when the latter is positioned therein.

The shade holder proper or skirt ,13 is made preferably of thin resilient sheet metal inany suitable or desirable form with depending means 23, which may be a flange, to receive screws 14 or other holding devices for fastening the shade 15 to the shade holder. Atthe top of the shade holder 13 is a cylindrical portion 24 of such diameter and length as tOnfit neatly within the shoulder 21 of the cap or its flange 22and the straight band 19, and is provided on its pe ripheral surface with one or more studs 25 to engage over said shoulder and sustain the shade holder when insertedin the cap 12. Close to each stud 25 the cylindrical portion the cap is given a short outward Patented July23, 1912.

24 is slotted, which slots 26 extend downwardly through the body of the skirt nearly to the flange 23 and divide the parts so slotted into spring sections, on ea of which is a stud 25. The upper edge of the t iylindrical portion 24 is protected and sti ened by an inturned flange 27. It has been found advantageous and convenientf tqjiwiden one of the slots .26 as shownat iw efer the passsage therethiirighbf the Iamps'withh Tkeyi30..,

Assuming that the capf12 and the. lamp socket- 10 are ingplace on the arm 11, the skirt or sh'ade holder 1 3 is attacheddo the cap by inserting the cylindrical portion 24 of said skirt into the open bottomcof the cap, The studs 25 which are beveled on their upper surface, and which are-preferably, formed by pressing out the material of the cylindrical portion; engage the edge-oi the ShOllldeI' 21 or its flange 22' and are forced inward thereby ;*the spring sections on which" they-aremounted' yielding to permit this. @As soonias 'the' s'tuds pass above the a and retainedtherein hy' the lugs 25 holds the skirt rigidly in1jplace in the cap' and always symmetrically positioned about the lamp. The top edge of the skirt'bearing against the part 17 of the cap prevents the skirt from rocking or wabbling or getting displaced, the shade therefore supportedby the skirt will always be in position, whether it be hung straight downward or at an an gle -"as its -weightcannot dislodgeit-. N9r can theskirt be withdrawn from theca-p by a direct pull owing to the hook-like action of the stud;- LThe shade h'til'der or skirt may be disconnected-from -the'cap by pressing inwardly on one of the sections until the stud on said section is disengaged from the shoul der when a downward pullon the skirt disconnects the parts.

It is to be noted that the bottom of the cap 12 is above the point of connection 28 between the body-ref the lamp socket 10 and its top 16 so that rnodifliculty will be encountered in connecting the lead in wires to the switch in the lamp tbody, notwithstanding theifact that the lamp socket is inclosed within the shade holder.

. The slots 26 besides serving the purpose described are also ventilating openings .to

permit the escape of heated air between the am bulb andjthe shade and shade holder. hat Lcl aini is:-,

1. A shade holder comprising a cap adapted to be attached to a support having a C11- .cular band and a terminal flange connected by a bead at its open;end, a skirt having its upper end slotted to form spring sections shaped to fit. snugly within the band and flange, and a lugoneach section to engage said bead and hold the skirt in position.

2'. A shade holder comprising a cap adapted to be rigidly attached to a support and having a bearing surface at its free edge, and an inturned hook-shaped shoulder rojecting inwardly from said bearing sur ace, a skirt having a cylindrical upper portion fitting neatly within the bearing surface of the cap, and locking ln s on the skirt adapted to engage the shoul er on the cap.

curely in place, one of said slots being. enlarged to permit passage of the lamp socket key.

A. A shade holder comprising a cap adaptedtobe rigidly attached .to a'support and having a bearing xsurfaceat its free edge, an inturned hook-s aped shoulder pro ect1ng inwardly from said bearing surface, and a bearing corner, a skirt havin a cylindrical upper portion fitting neatly within the hear: ing surface of the cap and against said corner, and spring actuated lockmg lugs on the skirt adapted to engage the shoulder on the I n testimony whereof I have hereunto set my hand in presence of two subscribing witnesses;
